The new PS Plus PSP emulator includes plenty of undiscovered functionalities, it even allows patches directly to the emulated Allegrex cpu.
The new ps plus psp emulator has a lot of undiscovered functionalities. It even allows patches directly to the emulated Allegrex cpu.
Not many CLI commands were added this time around. Very few commands have a description to their usage inside of the eboot.bin, everything else is just guesswork from the scene. Plenty of LUA commands need to be understood before the compatibility of games can improve. The PSP emulator has not gained the same popularity as the ps2 emulator due to the existence of an unofficial PPSSPP core in the unofficial Retroarch port for the PS4. As far as the compatibility and performance go, the Retroarch core is yet to be bested. This emulator may hold potential, but the potential can only go so far as it seems not to have support for gamedata installation, which in turn will render many games unplayable.
Sadly sony has not made it easy for users to use CLI commands. Since sony mostly uses lua patches for the psp releases, not many cli commands were added. Very few commands have a description to their usage inside of the eboot.bin. Everything else is just guesswork from the scene. The psp emulator has not gained the same popularity as the ps2 emulator because currently, there is an unofficial PPSSPP core in the unofficial retroarch port for the ps4. and as far as the compatibility and performance goes, the retroarch core is second to no one. This emulator may still hold potential, though sadly it does not seem to have support for gamedata installation. and that has led to many games becoming currently unusable. with an official retroarch release coming into ps4's way it seems delving deeper into the PSPHD emulator and the PS1's new psplus emulator is pretty useless.
